Teenage Mutant Ninja… Jaguars? Jellyfish? I think I’d like to see either one of those ideas developed 
I voted for Raph, influenced mainly by the first movie, where I identified with his pissed-off, Devil-may-care attitude at the time, and the *Turtles In Time *video game, where he was my go-to Turtle because he was by far the fastest and most mobile. I would rank Leo and Don a close 2nd and 3rd, in some order, but Mikey to me was always an attention-seeking doofus.
